END-WIPER MECHANISM FOR LASTING-MAOI-IINES- Specification of Letters retent. 1 Pat t d May 20, 1919,

Application filed June 28, 1915. Serial No.36,736.

To all whom it may concern:

Be it known that I, MATTHIAS BROOK, a citizen of the United States, residing at Boston, in the county of Suffolk, and Stateof Massachusetts, have invented certain Improvements in End-Wiper Mechanism for Lasting-Machines, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relatesto mechanism for shaping an end portion of a shoeupper and particularly to end lasting mechanism, being herein shown as embodied for illustrative purposes in the heel wiper mechanism of a lastinomachine similar to that shown in United States Letters Patent No. 1,018,477, granted February 27, 1912, on an application filed by me.

The general object of the inventionisto improve upper shaping mechanism and a more particular object 1s to provide end embracing wipers better adapted for wiping upper 'materials into lasted position than wipers heretofore employed.

One feature of the invention consists in end embracing wipers which are adjustable in length for shoes which are of different lengths or which offer opportunity for advantageous use of wipers for different distances from the end of the shoe. This feature of the invention is shown as embodied in heel wipers which can be extended at either or both sides of a heel seat to reach into the shank as far as conditions in that particular shoe or that style of shoe may require or will permit.

Another feature of the invention consists in wipers which are adjustable to different planes presented by different portions of the shoe bottom to which the wipers are to shape the stock. This feature of the invention is shown as embodied in a wiper one portion of which as for example, the portion of a heel wiper reaching over the shank of the shoe, can be adjusted relatively to another portion to locate its acting face out of the'plane of the acting face of said other portion such as the portion operating over the heel seat of the shoe. The end portion of the illustrated heel wiper has a resilient plate which can be deflected downwardly to adapt it the plane of the portion of the shank of the shoe into whlch the wiper reaches.

These and other features of thisinvention,

including certain details of construction and combinations of parts, will now be more fully described in connection with the accompanymg drawings and will then be pointed out in the claims. 1

Figure 1 of thedrawings is a side elevation of the rear portion of a lasting machine which is equipped withthe present .invei tion;

Fig. 2 is a plan view of the same, showing the wipers open and indicating' the rear portion of a shoe which is to be operated upon;

Fig. 2 is a fragmentary plan view illustrating a modified form of the wiper adjusting means; V

Fig. 4 isa transverse vertical sect-ion lookingi toward the left from line H on- Fig. .5; an V Fig. 5"is a plan view showing a wiper closed over a shoe bottom for comparison withFig.2.

' The lasting machine shown T comprises a toe rest 2 and a heel. post 3 supported by the frame 1 and by which a last with a shoe assembled upon itis sustained and fixed in position for the operation of the heel lasting mechanism upon theshoe materials The heel lastingmechanism comprises, as may be learned in greater detail from said prior patent, a carriage movable longitudinally on the frame to carry the wipers and a heel embracing band into proximity to the shoe where it is held by a latch 6. On the carriage is a rocking head by which the wipers may be adjusted about a transverse horizontal axis to the longitudinal inclination of'the last bottom.- Inthehead the wipers are adjustable by a. screw and. hand crank '7 about a horizontal axis extending longitudinally of the shoe to adapt the wipers to the transverse inclinationof the last bottom. The entire heel lasting'mechanism may also be adjusted about a verticalaxis located at lto adapt the wipers to cooperate uniformly with right and left crooked lasts. The wipers are operated to advance and close the shoe bottom by a hand lever 10 acting through a plunger having a cross-head to the opposite ends of which links 8 connect the two wipers for the right and left sides of the heel seat.

' In the embodiment of the invention herein shown each wiper comprises a plurality of members including a curved rear end member 12 and a straight-edged side member 14. The rear end member is pivoted to the open atinglink8 and its direction of movement is controlled by a cam slot 13 therein into which fits a fixed guide stud 15. Also the outer edge of ,eaohWipe-r member12 iscurved and is guided against an edge wall of the wiper confining recess in the head. The inner edgesrof the wiper members 12 are abutted together at their wiping edges and theguiding means are so .formed asto advance and turn said members from their shoe receiving position shownin Fig. 2 to the" relation to a shoe shown in Fig. 5;

Thewiper member l2 is formed with a wiping edge that extends from the rear end of the heel forwardly to and, as shown best in Fig.- 5, around the corner of the heel to the. side of theheel. The wiper member 12 'is cut away or otherwise formed on its. lower face with a guide channel to receive the wiper member 14 andpermit relative endwise movement between said two wiper members 12 and 14.

The members 12Iand 14 of a wiper are operatively connected by a stud 2O rising from the member l4-through a longitudinal slot- 21 in themember 12. The stud also extends upwardly into a transverse slot 23 in an overlying :plate 22. The member 14 1 may alsohazve a lateral flange on its inner edge, Fig. 4, which is guided in a groove in the adjacent wall .of the member 12. These connections provide for operating the wiper member 14 inwardly and outwardlyxwith and :bythe. wiper member 12 and for moving the member 12 longitudinally relatively .to member 14while the. plate 22 .restrains member -14from movin endwise; A similar arrangement by whic a side wiper member is caused to partake of the closing movement of an advancing and closing end wiper but is restrained from accompanying the end wiper in its advance movement is described and claimed in prior United States Letters Patent No. 1,188,616, granted upon my application Oll'Jlll'lS 27, 1916, and therefore no claim is here made to what is there disclosed.

The overlying plates 22 are movable, in accordance with the illustrated embodiment of this invention, longitudinally of the machine and of the shoe, being guided in ways out :for them in the cap plate 24, Fig. 3. The rear ends of the plates 22 have studs projecting up through longitudinal slots in the cap plate 24 and extending into-an adjusting bar 25. This bar is shown as centrally fulcrumed' on a screwstudi 26 to permit it to .be swung for adjusting one slotted plate 22 and side wiper member 14 forwardly and the plate 22 and wiper member 14 at the opposite side of the shoe backwardly. Adjust' ment of members 14 provides for making that wiper which operates at one side of the heel longer than that wiper which operates at the other side. This is important because many styles of lasts are so formed in the shank that the upper materials can advanta geously V, be worked into lasted position by the heel wipers for a substantially greater distance along the inner side of the shank than can be .done along the outer side of the shank. Simultaneous and proportional adjustment of the members 14 of: the opposed wipers gives the results required in shifting the wipers for right and left shoes.

The adjusting bar 25, after havingpefiected simultaneous adjustment of the .two side wipers in opposite directions, can be secured in angular position by a clamping screw 27 which cooperates with a slotted link 28. If simultaneous adjustment is not desired the modified construction shown in Fig. 2 may be used, the adjusting bar being divided at the stud 26, forming complemental bars 25, and duplicate securing means 27 28 being used at the two sides of the heel.

The fulcrum screw 26' is threaded into a slide 29which is dove-tailed into a "longitudinal slideway in the cap plate 24. The slide 29 can be moved along the slideway to adjust the side wiper members 1-4 endwise to lengthen or shorten the heel wipers according to the size of shoe to be lasted. When screwed down against the cap plate 24the screw 26 binds the slide 29 in, adjusted position. WVhen the screw 26 is. loosened one end of the bar 25. can be adjusted forwardly or backwardly, fulcriuned on the other end of p 1 or one wiper member 14 lengthwise without ad usting the other wiper member.

The/front portion of each wiper member 14 is cut away on its lower side and a resilient plate 30 is set into it and secured in place as by a screw 31 shown in Fig. 4, the front end portion of each resilientplate being free to be sprung downwardly by a screw 32 as in Fig. 3. It will be understood that the wiper members 12,14 are soarranged relatively that their lower wiping faces are flush, or lie in the same plane. The rear portion of resilient plate 3.0 will also be flush with member 14 and in the same plane with it and the frontv portion of said plate 30 may be normally in that plane. The, feature of the invention embodied in this construction deals with that formation .of many at one side of the last, as the inner side,

than at the outer side. Heretofore the 1st wipers could not effectively wipe in the upper on the low side because of being held in too high aplane by the high side of the ,last. This difliculty is particularly apparent when long wipers are used, such as herein contemplated, which reach well forwardly over the shank of. the shoe. By this invention the plate 30 cooperating with the low side of the last can be sprung down by its adjusting screw 32, as indicated in Fig. 3, to locate the effective acting face of the side wiper in the plane required for dealing properly with the low side of the last. If the plate30 is normally "inclined upwardly, as above suggested, the wiper on one side can deal with an abnormally high side of a last *inthe shank while the wiper on theother side can deal with such a low side as that described. It will be noted that the adjustment provided by the parts 30, 32 is equivalent to twisting, or bending downwardly the'acting face of one wiper at its front end,'as distinguished from adjusting the wipers as a whole to" the longitudinal and the transverse inclinations of the last bottom, whichis well known. 3 3 i When a lasting 'or' other machine for shaping uppers is equipped with this invention the side wiper members are adjusted longitudinally for the length ofshoe or length of heel seat to be lasted, and, if the last is so shaped that one wiper canadvantageously operate farther forwardly into the shank than the other can, the adjusting bar 25 is adjusted angularly to set one side member let ahead of the other. If the shank portion 'of the last reached by the end portionof either of the wipers is outof the plane of the heel seat the screws 32 are set to adjust the resilient face plates 30 to the requirements of the last. The wipers may then be operated as usual to shape the flange portions ofthe upper materials to fit snugly to thebottoni'face of the shoe. j v Having explained the nature of. the invention and described how it maybe used, I claim-as new and desire to secure by Letter-s Patent of the United States 1.
